Frozen Kong recipes and lick mat ideas are two of the simplest ways to keep a dog mentally stimulated, and you probably already have everything you need in the fridge. A stuffed, frozen Kong can keep most dogs busy for 20 to 40 minutes, while a loaded lick mat delivers a shorter but intensely focused session that’s especially useful for calming anxious dogs or slowing down fast eaters.
The recipes don’t need to be complicated. A smear of peanut butter and a handful of kibble will do the job. But if you want to mix things up and give your dog something genuinely exciting, the ideas below cover everything from beginner-friendly fillings to layered frozen combinations that’ll challenge even the most experienced Kong-wrecking dogs.
Stuff a Kong with a base layer (kibble, banana, pumpkin), add a binding layer (yoghurt, peanut butter, wet food), seal the small hole with cheese or a blueberry, and freeze for 3–4 hours. For lick mats, spread a thin layer of yoghurt, mashed banana, pumpkin or wet food, then freeze for 1–2 hours. Both provide mental stimulation, reduce anxiety and slow down fast eaters. Always use xylitol-free peanut butter and supervise your dog with lick mats.
Why Frozen Enrichment Works So Well
The repetitive licking action required to work food out of a Kong or off a lick mat triggers the release of endorphins in dogs, which has a naturally calming effect. That’s why vets and trainers frequently recommend frozen enrichment for dogs dealing with separation anxiety, storm phobia, crate training struggles, or just general boredom.
Freezing the contents takes it up a notch. An unfrozen Kong might last five minutes. A frozen one can keep a dog occupied for 20 to 40 minutes depending on the recipe and the dog’s experience. For lick mats, freezing extends the session from a couple of minutes to 10–15 minutes, which is often long enough to get through a nail trim or a bath without drama.
Beyond the calming benefits, frozen Kongs and lick mats slow down dogs that eat too quickly. Gulping food can lead to digestive issues, excess gas and in larger breeds, a risk of bloat. Spreading a meal across a lick mat or packing it into a Kong turns a 30-second inhale into a genuine activity.
What You Need to Get Started
Choosing a Kong
The Kong Classic (red) suits most adult dogs. The Kong Extreme (black) is built for power chewers and is only a few dollars more. For puppies, the Kong Puppy (pink or blue) is softer on developing teeth. Size matters: a Kong that’s too small for your dog is a choking hazard, and one that’s too big won’t hold their interest. Kong’s website has a sizing guide based on your dog’s weight.
To freeze a Kong upright without it tipping, stand it in a mug or use a Kong holder. If the recipe is liquid-heavy, seal the small hole at the bottom with a chunk of cheese, a large blueberry, or a strip of painter’s tape.
Choosing a Lick Mat
The LickiMat brand is widely available in Australian pet stores and comes in several patterns. The LickiMat Buddy works well for thicker spreads, while the LickiMat Soother is better for paste-like mixtures. For dogs that power through flat mats in seconds, the LickiMat Wobble adds extra challenge by rocking around while the dog licks. Most lick mats are made from food-grade silicone and are dishwasher safe on the top rack.
A word on supervision: lick mats are thinner than Kongs, and a determined chewer can damage them. Always supervise the first few sessions until you know your dog won’t try to eat the mat itself.
Frozen Kong Recipes
The key to a good frozen Kong is layering. A solid base holds everything together, a binding layer fills the gaps, and a seal at the bottom stops leaks during freezing. Here are some tested combinations using ingredients that are easy to find in Australian supermarkets.
Peanut Butter and Banana
Mash half a banana and mix it with a tablespoon of xylitol-free peanut butter. Spoon it into the Kong, packing it down firmly. Seal the small hole with a chunk of banana and freeze for 3–4 hours. This one is a crowd-pleaser and uses ingredients most people already have on hand.
Pumpkin and Cream Cheese
Combine a quarter cup of plain canned pumpkin (not pumpkin pie filling, which contains spices and sugar) with a tablespoon of cream cheese and a splash of water. Stir until smooth, spoon into the Kong and freeze. Pumpkin is gentle on digestion and low in calories, making this a solid option for dogs on a weight management plan.
Kibble and Bone Broth
Fill the Kong about two-thirds full with your dog’s regular kibble. Pour in low-sodium bone broth (check the label for onion and garlic, which are toxic to dogs) until the kibble is just covered. Seal the bottom and freeze overnight. This is a great low-calorie option because it uses food your dog is already eating, so it doesn’t add extra to the daily intake.
Yoghurt Berry Freeze
Mix a couple of tablespoons of plain, unsweetened Greek yoghurt with a handful of blueberries or diced strawberries. Spoon into the Kong in layers, pressing down between each one. Freeze for 3–4 hours. The berries add flavour and antioxidants without too many calories. Avoid flavoured yoghurts, which often contain artificial sweeteners or excess sugar.
Sweet Potato and Wet Food
Mash a small amount of cooked sweet potato and layer it with a spoonful of wet dog food inside the Kong. Pack it down tightly and freeze. Sweet potato is nutrient-dense and has a thick texture that makes the Kong harder to empty, which is perfect for dogs that blast through simpler recipes in minutes.
Lick Mat Ideas That Actually Last
Lick mats work best with spreadable, paste-like textures. The trick to making them last is freezing: spread the mixture thin and even across the mat using a spatula or butter knife, then freeze for 1–2 hours until solid.
Classic Peanut Butter Spread
Spread a thin layer of xylitol-free peanut butter across the mat. Press some kibble or small training treats into the surface for added texture and challenge, then freeze. Simple, effective, and most dogs go absolutely wild for it.
Mashed Banana and Yoghurt
Mash a ripe banana and mix with a tablespoon of plain Greek yoghurt. Spread the mixture evenly across the mat and freeze. The banana makes it sticky enough to stay in the mat’s grooves, and the yoghurt adds a probiotic boost. This is one of the easiest recipes to put together on a busy morning.
Pumpkin and Wet Food Swirl
Spread alternating patches of canned pumpkin and wet dog food across the mat. Use a toothpick or skewer to swirl them together lightly. Freeze for 1–2 hours. The different textures and flavours keep dogs engaged for longer than a single-ingredient spread.
Sardine Smash
Mash a tin of sardines in spring water (not brine) with a fork. Spread across the mat and press a few small pieces of carrot or zucchini into the surface. Freeze. Yes, it smells. But dogs lose their minds over it, and sardines are packed with omega-3 fatty acids that support skin and coat health. This one is best served outdoors or on an easy-to-clean surface.
Watermelon Ice Block
Blend seedless watermelon chunks into a smooth liquid. Pour over the lick mat and freeze. This is particularly good on hot Australian summer days (December through February) when dogs need help cooling down. Watermelon is low-calorie, hydrating, and most dogs love the taste. Use a mat with deeper grooves like the LickiMat Buddy to stop the liquid from running off before it freezes.
How to Build a Layered Frozen Kong
If you want to step up from basic fillings, layering creates a Kong that’s harder to empty and more rewarding to work through. Here’s the method.
- Seal the small hole. Press a chunk of cheese, a large blueberry, or a piece of banana into the small opening at the bottom. Alternatively, use painter’s tape on the outside.
- Add a base layer. Fill about a third of the Kong with something solid: kibble, diced carrot, blueberries, or small training treats. This gives the dog something to work towards at the end.
- Add a binding layer. Spoon in a wet, sticky mixture: mashed banana, pumpkin, yoghurt, peanut butter, or wet dog food. Pack it down firmly to fill the gaps between the solid pieces. This is the layer that makes the Kong last.
- Repeat and cap. Add another layer of solids, then another binding layer. Cap the wide opening with a thick smear of peanut butter, cream cheese, or yoghurt so the dog has something to lick off the top while they work on the frozen core.
- Freeze for 3–4 hours or overnight. Stand the Kong upright in a mug or holder. A full freeze makes a massive difference to how long the Kong lasts. A partially frozen Kong will be demolished in minutes; a rock-solid one is a genuine 30-minute challenge.
Foods to Avoid and Safety Tips
Not everything in the kitchen is safe for dogs. Before you start experimenting, know the boundaries.
The biggest risk with frozen Kong recipes and lick mats is xylitol, an artificial sweetener found in some peanut butters, yoghurts, and sugar-free products. Xylitol is extremely toxic to dogs and can cause life-threatening drops in blood sugar and liver failure. In Australia, xylitol in peanut butter is less common than in the US, but it does appear in some keto and high-protein nut butter brands. Always read the ingredients label before using any peanut butter with your dog. If it says xylitol, birch sugar, or “sugar-free,” don’t use it.
Other foods to keep out of your dog’s Kong and lick mat: chocolate, grapes and raisins, macadamia nuts, onion, garlic, and avocado. Cooked bones should also never go inside a Kong, as they can splinter.
Watch the calories, too. A Kong stuffed with peanut butter and cheese is delicious but calorie-dense. If you’re using enrichment daily, factor the fillings into your dog’s total food intake for the day. Lower-calorie options like pumpkin, watermelon, cucumber and kibble soaked in broth are better for everyday use. Save the peanut butter-heavy recipes for special occasions or training days.
Always supervise your dog with lick mats, especially during the first few sessions. Some dogs will try to chew the mat once the food is gone. Kongs are built to withstand heavy chewing, but even a Kong should be replaced if it starts to show cracks or missing pieces.
When to Use Frozen Kongs and Lick Mats
Frozen enrichment isn’t just a treat. Used at the right moments, it can reshape your dog’s emotional response to situations they find stressful or overstimulating.
Give a frozen Kong when you leave the house to ease separation anxiety. The dog associates your departure with something good, and the activity keeps them busy through the first 20–30 minutes, which is when anxiety tends to peak. Drop a loaded lick mat into the crate during crate training to build a positive association with the space. Stick a lick mat to the bath wall (most have suction cups) to keep your dog occupied and calm during bath time, nail trims, or grooming sessions.
During Australian summer, frozen enrichment doubles as a cooling tool. A frozen Kong filled with broth, a lick mat covered in frozen watermelon puree, or even plain frozen yoghurt spread on a mat can help bring a dog’s body temperature down after exercise.
For dogs recovering from surgery or injury who are on restricted exercise, frozen Kongs and lick mats provide mental stimulation without physical strain. A bored, recovering dog is a dog that’s going to find trouble. Enrichment keeps the brain busy while the body heals.
When to Get Professional Help
Frozen Kongs and lick mats are great tools, but they’re not a replacement for addressing underlying behavioural issues. If your dog’s anxiety is severe enough that they can’t settle even with enrichment, or if they become destructive, pant excessively, or refuse to eat when left alone, it’s worth speaking with your vet or a qualified reward-based trainer. Enrichment can be part of a broader plan, but it works best when combined with proper training and, where needed, veterinary support.
Frequently Asked Questions
How long does a frozen Kong last?
A fully frozen Kong typically keeps a dog busy for 20 to 40 minutes, depending on the recipe, the dog’s size and experience. Dogs new to Kongs may give up faster, so start with a partially frozen or unfrozen version and work up to fully frozen over a few sessions.
Can puppies have frozen Kongs and lick mats?
Yes. Use a Kong Puppy (softer rubber) and start with simple, gentle fillings like plain yoghurt or soaked kibble. Avoid hard frozen Kongs for very young puppies, as their teeth are still developing. Lick mats are fine for puppies from around eight weeks, but always supervise.
What peanut butter is safe for dogs?
Use a peanut butter that contains only peanuts (and possibly salt). Avoid any product labelled “sugar-free” or containing xylitol, birch sugar, or artificial sweeteners. In Australia, most standard supermarket peanut butter brands (like Bega, Pic’s, and Mayver’s) do not contain xylitol, but always check the label, especially with keto or high-protein varieties.
How often can dogs have frozen enrichment?
Daily is fine, as long as the fillings are factored into the dog’s total daily food intake. For everyday use, stick to lower-calorie options like pumpkin, kibble in broth, or watermelon. Save the richer recipes (peanut butter, cheese, cream cheese) for a few times a week or when the dog needs extra help settling.
Can I put my dog’s whole meal in a Kong?
Absolutely. Many trainers recommend feeding part or all of a dog’s daily meal through enrichment rather than a bowl. Soak the kibble in a little water to soften it, mix in a binding ingredient like yoghurt or wet food, pack it into one or two Kongs, and freeze overnight. It turns breakfast into a 30-minute brain workout.
